Role Overview

We’re currently looking for an experienced RF Test Engineer to join a dynamic product-focused environment.

Job Responsibilities:

• Design and develop RF test setups and fixtures tailored for low-volume production.
• Create and execute comprehensive RF test strategies for both new developments and existing products.
• Work hands-on with RF lab equipment (e.g., spectrum analyzers, VNAs, oscilloscopes) to perform accurate measurements.
• Maintain and troubleshoot legacy test systems, fixtures, and software down to component level.
• Build and enhance automated testing and calibration processes for RF systems.
• Investigate and resolve RF performance and signal integrity issues.
• Automate data collection, analysis, and reporting for test results.
• Contribute to design reviews with a strong focus on testability and product reliability.
• Collaborate closely with cross-functional engineering teams throughout the product lifecycle.

Job Requirements:

• Experience in RF testing within product development or manufacturing environments.
• Strong exposure to lab-based testing and measurement setups.
• Ability to read and interpret circuit schematics and hardware designs.
• Hands-on experience with PCB debugging at component level.
• Practical skills in SMT soldering and hardware rework.
• Comfortable creating custom tools and fixtures (3D printing / laser cutting is a plus).
• Basic experience with CAD tools (e.g., Fusion 360, SolidWorks).
• Experience testing RF systems such as beamforming modules, GPS receivers, or similar.
• Programming experience (Python or MATLAB) for test automation.
• Strong understanding of RF measurement techniques (e.g., EVM, large-signal S-parameters, power amplifier characterization).
• Comfortable working in a collaborative, multicultural engineering environment with strong communication skills.
